Walter Jon Williams has published twenty novels and short fiction collections. Most are science fiction or fantasy -Hardwired, Voice of the Whirlwind, Aristoi, Metropolitan, City on Fire to name just a few - a few are historical adventures, and the most recent, The Rift, is a disaster novel in which "I just basically pound a part of the planet down to bedrock." And that's just the opening chapters. Walter holds a fourth-degree black belt in Kenpo Karate, and also enjoys sailing and scuba diving. He lives in New Mexico with his wife, Kathy Hedges.
